$55.00 inexpensive, but not for the HHR, now there is no eminent danger, however the Cobalt is considerably lighter than the HHR.

The steel ones bolted straight in, the bolt holes were all in the correct place. the car is driving fine and no noise. The steel control arms were a little heavier than the aluminium ones but only by a lb or 2 so i don't see that will make much difference. I know i will be a lb or 2 heavier after new year ; )

x2 what Donbrew says - it has nothing to do with the weight difference between the steel and the proper ones. It's the strength difference. Yes they fit, but needing an alignment makes one wonder.

We cannot approve the use of the steel ones at all. You are using them at your own risk.
